I started drinking this tea to help my energy after having my son. I had to return to work and needed an alternative to coffee to help me through the work days after my sleepless nights up with the baby. It tastes great and I can tell that it really helps with my mental clearity. And it does NOT give you the jittery-coffee side-effects. I did not like the tropical flavors of yerba mate, but really enjoyed this combonation of flavors.
